WHEEL-PRESS.

SPECIFICATION forming part of Letters Patent No. 504,030, dated August 29, 1893. Application filed July 20, 1892. Serial IIa-440,596. (No model.)

To all whom it may concern.-

Be it known that I, HENRY D. GORDON, of Altoona, county of Blair, State of Pennsylvania, have invented a certain new and useful Improved Wheel-Press, of which the following is a true and exact description, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to Wheel presses such as are used for pressing axles into and out of the hubs ofl car and engine wheels; as heretofore constructed these presses h ave not been built to accommodate themselves to different sizes of wheels; consequently in use there is a good deal of trouble and delay arising from the necessity of adjusting the wheel to the proper height relative to the press.

The object of my inventionls to overcome this difficulty by making the press itself vertically adjustable so that its operative parts can always be brought to the proper position to operate upon a wheel standing upon the floor, no matter what the height of the Wheel may be, and this device of a vertically adjustable wheel press is the leading feature of my invention, the details and subordinate parts of which will be best understood as described in connection with Ithe drawings in which my invention is illustrated as applied to a familiar type of wheel press, and in which- Figure 1 is a front elevatlon of the press; Fig. 2 an elevation looking from the left-hand end of Fig. l; Fig. 3 a cross-section on the line :o a; of Fig. l; Fig. 4 a perspective view illustrating a detail of construction, and Fig. 5 a perspective view illustrating one of the supports further to be described.

A indicates the foundation upon which the press is erected; on this foundation is formed a cavity C with vertical extensions B', said cavities being' below the oor A of the press. In these cavities or wells B are secured hydraulic presses B secured to the bottoms of castings C which are placed above the presses, and which, as their function is to guide the supports upon which the press 1s sustained, I will hereinafter refer to as guides. These guides, as shown consist of heavy rectangular castings having on the inside of their front and back sides racks C2.

. F indicates the supporting casting which is vertically movable in the guide O.

E and Gare upright standards constituting part of the press, and which support all the operative press mechanism. These standards are bolted securely to the supporting castings F and, as shown, are provided with extensions E2 which extend down through an opening F5in the top of the support F and are formed wit-h slots as shown, to receive the ends of a cross-bar H which extends across from one standard to the other asshown in Fig. l.

In the construction shown a casting D2 is secured to the bottom of the extension E2 by means of bolts D4 which also serve to hold the cross-bar H in position; these castings D2 I form with an extension Ds which extends out to an opening F in the support F and serves a purpose hereinafter to be described. The pistons D of the hydraulic rams B extend upward through a suitable stuffing box as indicated atD and rest against the bottoms of the castings D2.

At the tops of the standards E and G are slots E4 and G4 adapted to receive a cross-bar I running parallel to the bar H; these crossbars serving to support and guide the adjustable standard J which is supported on bar H by means of wheels J2 .I2 and provided with a proper cavity .I corresponding with a similar cavity E3 in the standard E to receive the axle. The bar I also supports the traveling carriage K having a threaded bolt K-fextending down from it upon which is secured the hook-support K', K8 being the hook and K2 a binding nut. The standard G (which I have not shown in its lower part in detail as -it corresponds exactly with the lower part of and attachments to the standard E) supports on a sprocket G3 the driving shaft L4 which communicates motion through a connecting rod or rods L5 with the piston L5 of a pump L7 connected by pipes L8 with a reservoir L9, and also connecting with the ram L, the head of which is indicated by the letter L', L2 indicating a chain which is attached to the head of the ram and runningbackward over a pulley is attached also to a weight L3 which serves to draw the ram back after it has been forced forward by the action of the pump. All these parts are of familiar and well un- IOO derstood construction, and need not be further referred to.

In appropriate openings F2 and F2 of the supporting casting F are pivoted pawls R in such position that they will engage the racks C2 and hold the supporting casting and the parts sustained upon it at any desired position. Any equivalent locking device maybe used instead of racks and pawls, which, however, are a very convenient lock for the purpose. As shown the pawls are provided with lever arms R and R2 extending in opposite directions and connected by a bar R3, by shiftingwhich the pawls are simultaneously en;

gaged or disengaged with the rack. The bar R2 is shifted by a lever R6 (see Fig. l) connected with the rock shaft R5 to which shaft is attached a lever arm R4 connecting with the rod R3 (see Fig. 3).

While any convenient mechanism may be employed for raising the supports F and the mechanism sustained upon them, hydraulic rams such as shown are in many respects peculiarly adapted for the purpose and when used they can be connected and actuated by the same pump which actuates the ram of the wheel press; thus, as shown in the drawings, a pipe M provided with a valve M which leads to the two rams B, a sliding joint M2 being provided in this pipe to permit of the vertical adjustment of the standard G which supports the pump. It is, however, impossible to so proportion the rams that they will raise the two ends of the press simultaneously because the center of gravity of the press is necessarily changed from time to time particularly by the adjustment of the upright post J. I overcome this difficulty, however, by means of the device best shown in Fig. 4, that is to say, I secure to the guides, shafts N placed near their tops, and shafts N near their bottoms, the shafts being above and below the extreme positions of the supporting castings F. To this casting, or as shown, to the casting D2 which is secured to it and substantially forms a part of it I attac-h chains I? and IJ which chains are passed over pulleys C O and 02 as shown in the drawings. Each chain connects with the two supports in such a way that a lnovement of one support cannot take place without a similar and simultaneous movement in the other support.

The operation of the device is as follows: An axle is hung in the hooks K2, and properly adjusted in front of the ram plunger L by means of the threaded bolt K4 and nut K2; a car wheel is then rolled into position on the Hoor A so that its center will be in the same vertical plane as the axle and ram plunger L. By now raising or lowering the standards E G and the ram C and the axle, all carried by said standard by means of the hydraulic rams B B, the axle and the ram L may be brought directly in line with the hole in the hub of the wheel into which it is designed to force the said axle. The ram L is now put in operation and the axle pressed into the hole in the wheel hub in the usual manner, the wheel being held from lateral displacement by the adjustable standard J. This sort of wheel press and its mode of operation are well known being illustrated in lmghts ll'echanicalctionary (page 2767, edition of 1884) and it is therefore not deemed necessary to show the wheel or axle in position in the press.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is
